Influenza Treatment with Antiviral Agents Dosing Recommendations * Due to seasonal influenza A (H1N1) resistance to oseltamivir, patients with suspected seasonal influenza A (H1N1) virus infection should be treated with zanamivir or alternatively with a combination of oseltamivir and an adamantane if zanamivir use is contraindicated (rimantadine is preferred over amantadine because of an increased risk of adverse events associated with amantadine).
The recommended alternative to zanamivir in patients with laboratory evidence of influenza A, a negative test result, or no testing is the combination of oseltamivir plus rimantadine (Flumadine).
The data also show that virus is resistant to amantadine and rimantadine but the organism continues to remain susceptible to oseltamivir and zanamivir.

Tom Jefferson and his colleagues from the Cochrane Vaccines Field examined evidence from trials on the efficacy of all four flu drugs: Tamiflu, Relenza, Amantadine, and Rimantadine. They strongly warn against relying on drugs to stamp out a potential avian flu pandemic and believe complacency will deter the use of public-health measures, such as hygiene and isolation, to stop the spread of infection.
